CAUTION
Adjust both seat cushions to the
same position and align both seat-
backs at the same angle when a
person sits in the third seat center
position. Otherwise, the person can-
not wear the seat belt properly and
this may cause serious injuries in
a collision.
Avoid reclining the seatback any
more than needed. The seat belts
provide maximum protection in a
frontal or rear collision when the
passengers are sitting up straight
and well back in the seats. If you
are reclined, the lap belt may slide
past your hips and apply restraint
forces directly to the abdomen or
your neck may contact the shoulder
belt. In the event of a frontal colli-
sion, the more the seat is reclined,
the greater the risk of death or per-
sonal injury.
BEFORE FOLDING UP THIRD SEATS
1. Stow the third seat belt buckles as
shown in the illustration.
NOTICE
To prevent damage to the seat belt
buckles, they must be stowed before
you tumble the seatback.
2. Make sure the shoulder belt passes
through the hanger when folding the
third seats.
This prevents the shoulder belt from being
damaged.
CAUTION
The seat belt must be removed from
the hanger when the seat belt is in
use.
